Provided is a new product-sum operation circuit having excellent convenience or reliability. In addition, a novel neuron circuit with excellent convenience or reliability is provided. A sum-of-products arithmetic circuit having a sum-of-products arithmetic unit and an amplifier, wherein the sum-of-products arithmetic unit is supplied with a group of input signals and a group of weight information, and is based on the sum-of-products value of the group of input signals and the group of weight information. Generate a first current and supply the first current. The amplifier is electrically connected to the product-sum calculator, is supplied with the first current and the bias voltage, generates a product-sum signal, and supplies the product-sum signal. The sum-of-products signal has a voltage based on the first current between the sum-of-products signal and the bias voltage.
